Martha Delgado is a leading figure in the environmental movement involved in political society in Mexico. Her leadership results from over 20 years of experience in various civil society organizations dedicated to sustainable development and 15 years of experience in public administration at the federal and local levels.

GLOBE spoke with Martha about her work with the Global Cities Covenant on Climate Secretariat and in-line with her participation at the upcoming GLOBE 2014 Conference, taking place in Vancouver, Canada, from March 26-28.

GLOBE: From 2006-2012, you served as Mexico City’s minister of environment and were involved with the development of its Climate Action Plan, “Plan Verde” (Green Plan), and Bicycle Mobility Strategy.  What was the single greatest challenge for you in engaging a mega-city with a population the size of Mexico City’s to take widespread action?

Martha Delgado: Mexico City used to be known as the most polluted city in the world. Converting this old image into a very different one was our challenge – it can´t be done just by organizing a good communications campaign. The vision, goals, and citizens’ behavior must be transformed in order to transform the city into a great place for living.

GLOBE: You now serve as the director general of the Global Cities Covenant on Climate Secretariat.  From your experience, what are three of the top actions that cities around the world can take in order to adapt their communities to a changing climate?

MD: Sustainable transportation must be strongly promoted as a priority for mayors and municipal governments. Private sector must make commitments to energy efficiency programs. And citizens should rethink and change their entire consumption patterns.

GLOBE: Many cities around the world are making unprecedented investments in sustainability, but lingering challenges remain about measuring and reporting on the success of these initiatives. What are some of the key metrics and performance indicators that can be used to measure and track a cities progress to becoming more “resilient”?

MD: Definitely having an Adaptation Program for the city is a very good way to start. It should include the evaluation of the risks for those cities, and also the strategies and actions to take for reducing their vulnerability. Some important indicators are also related connected to the ability of a city to react to climate disasters, the investments on infrastructure to prepare the city for extreme weather events, and the level of awareness of the citizens about these challenges.

GLOBE: You will be joining other urban sustainability leaders from around the world at GLOBE 2014 this March 26-28 in Vancouver, Canada, as a speaker in the “Building Resilient Cities” theme. What message do you hope to bring to the international delegates and audience that will be attending GLOBE 2014?

MD: Despite of the strong leadership and extraordinary work displayed for UNFCCC climate negotiations, national governments have been uncommitted, with low levels of ambition coming from the negotiators. The great hope for fighting global warming is found in the leadership of the mayors of the world, those with fewer resources but a greater understanding and vision, who are taking strong and inspiring actions to reduce GHG emissions and adapt their communities to global warming. Local governments should be recognized and supported in order to exercise this leadership and assume these big responsibilities.

Carbon dioxide removal revenues worth £2bn a year by 2030

Engineered greenhouse gas removals will become "a major new infrastructure sector" in the coming decades says the UK's National Infrastructure Commission

Carbon dioxide removal revenues could reach £2bn a year by 2030 in the UK with costs per megatonne totalling up to £400 million, according to the National Infrastructure Commission

Engineered greenhouse gas removals will become "a major new infrastructure sector" in the coming decades - although costs are uncertain given removal technologies are in their infancy - and revenues could match that of the UK’s water sector by 2050. The Commission’s analysis suggests engineered removals technologies need to have capacity to remove five to ten megatonnes of carbon dioxide no later than 2030, and between 40 and 100 megatonnes by 2050.

The Commission states technologies fit into two categories: extracting carbon dioxide directly out of the air; and bioenergy with carbon capture technology – processing biomass to recapture carbon dioxide absorbed as the fuel grew. In both cases, the captured CO2 is then stored permanently out of the atmosphere, typically under the seabed.

The report sets out how the engineered removal and storage of carbon dioxide offers the most realistic way to mitigate the final slice of emissions expected to remain by the 2040s from sources that don’t currently have a decarbonisation solution, like aviation and agriculture. 

It stresses that the potential of these technologies is “not an excuse to delay necessary action elsewhere” and cannot replace efforts to reduce emissions from sectors like road transport or power, where removals would be a more expensive alternative.  

The critical role these technologies will play in meeting climate targets means government must rapidly kick start the sector so that it becomes viable by the 2030s, according to the report, which was commissioned by government in November 2020. 

Early movement by the UK to develop the expertise and capacity in greenhouse gas removal technologies could create a comparative advantage, with the prospect of other countries needing to procure the knowledge and skills the UK develops.

The Commission recommends that government should support the development of this new sector in the short term with policies that drive delivery of these technologies and create demand through obligations on polluting industries, which will over time enable a competitive market to develop. Robust independent regulation must also be put in place from the start to help build public and investor confidence.

While the burden of these costs could be shared by different parts of industries required to pay for removals or in part shared with government, the report acknowledges that, over the longer term, the aim should be to have polluting sectors pay for removals they need to reach carbon targets.

Polluting industries are likely to pass a proportion of the costs onto consumers. While those with bigger household expenditures will pay more than those on lower incomes, the report underlines that government will need to identify ways of protecting vulnerable consumers and to decide where in relevant industry supply chains the costs should fall.

Chair of the National Infrastructure Commission, Sir John Armitt, said taking steps to clean our air is something we’re going to have to get used to, just as we already manage our wastewater and household refuse. 

"While engineered removals will not be everyone’s favourite device in the toolkit, they are there for the hardest jobs. And in the overall project of mitigating our impact on the planet for the sake of generations to come, we need every tool we can find," he said.

“But to get close to having the sector operating where and when we need it to, the government needs to get ahead of the game now. The adaptive approach to market building we recommend will create the best environment for emerging technologies to develop quickly and show their worth, avoiding the need for government to pick winners. We know from the dramatic fall in the cost of renewables that this approach works and we must apply the lessons learned to this novel, but necessary, technology.” 

The Intergovernmental Panel on Climate Change and International Energy Agency estimate a global capacity for engineered removals of 2,000 to 16,000 megatonnes of carbon dioxide each year by 2050 will be needed in order to meet global reduction targets. 

Yesterday Summit Carbon Solutions received "a strategic investment" from John Deere to advance a major CCUS project (click here). The project will accelerate decarbonisation efforts across the agriculture industry by enabling the production of low carbon ethanol, resulting in the production of more sustainable food, feed, and fuel. Summit Carbon Solutions has partnered with 31 biorefineries across the Midwest United States to capture and permanently sequester their CO2 emissions.  

Cory Reed, President, Agriculture & Turf Division of John Deere, said: "Carbon neutral ethanol would have a positive impact on the environment and bolster the long-term sustainability of the agriculture industry. The work Summit Carbon Solutions is doing will be critical in delivering on these goals."

McKinsey highlights a number of CCUS methods which can drive CO2 to net zero:

  • Today’s leader: Enhanced oil recovery Among CO2 uses by industry, enhanced oil recovery leads the field. It accounts for around 90 percent of all CO2 usage today
  • Cementing in CO2 for the ages New processes could lock up CO2 permanently in concrete, “storing” CO2 in buildings, sidewalks, or anywhere else concrete is used
  • Carbon neutral fuel for jets Technically, CO2 could be used to create virtually any type of fuel. Through a chemical reaction, CO2 captured from industry can be combined with hydrogen to create synthetic gasoline, jet fuel, and diesel
  • Capturing CO2 from ambient air - anywhere Direct air capture (DAC) could push CO2 emissions into negative territory in a big way
  • The biomass-energy cycle: CO2 neutral or even negative Bioenergy with carbon capture and storage relies on nature to remove CO2 from the atmosphere for use elsewhere
