Singapore's Robust Plan for Net Zero by 2050
Singapore has made a bold pledge to lower its carbon emissions to between 45 million and 50 million tonnes by 2035, showcasing its dedication to climate action as other nations pull back their efforts.
The commitment, declared to the UN, signifies a crucial step in Singapore's journey towards achieving net-zero emissions by 2050.
"Singapore is a liveable and sustainable city, with clean air and a clean living environment, a robust and diversified supply of water and beautiful green spaces," says Masagos Zulkifli, Vice Chairman of the People’s Action Party of Singapore.
Ranked as the second most sustainable city in Asia and eighteenth globally by 2024 Sustainable Cities Index, Singapore has ambitious plans moving forward.
A steady journey toward clean air
Rather than postponing major emissions cuts until mid-century like some countries, Singapore’s 2035 target indicates a consistent reduction path rather than a sudden drop.
The nation expects its emissions to peak at 64.43 million tonnes in 2028, reducing to 60 million tonnes by 2030 and further by 2035.
This approach highlights Singapore's commitment to immediate action, instead of waiting for decarbonisation technologies to become more affordable.
Climate scientists have criticised strategies that overly depend on future technological advancements rather than implementing existing solutions now.
Strategic investments in renewable solutions
Singapore faces geographic constraints that challenge the establishment of large-scale renewable projects such as expansive solar farms, leaning heavily on imports for its energy needs.
To tackle this, the government is ramping up investments in alternative solutions, including offshore solar panels and clean energy imports from neighbouring countries.
A significant portion of Singapore's emissions, 36.5% in 2022, stems from the power sector.
Addressing this, the government plans to explore cutting-edge technologies like small modular nuclear reactors and hydrogen energy, which could dramatically reduce emissions once they become feasible.
Prime Minister Lawrence Wong, in his Budget 2025 speech, disclosed that Singapore had recently signed agreements with the US to collaborate on nuclear energy projects.
“Within the government, we will reorganise ourselves to provide greater emphasis on this work,” he said.
“We will need new capabilities to evaluate options, and to consider if there is a solution that Singapore can deploy in a safe and cost-effective way.”
The country plans a hefty investment of US$3.73bn in clean energy in the upcoming years as detailed by Prime Minister Wong.
The broader impact on economy and society
Singapore's strategy to cut carbon emissions is expected to extend beyond energy production, potentially affecting the broader economy and individual households.
Businesses might face tighter environmental regulations, and consumers could endure higher energy prices as a result of increased carbon taxes.
Singapore acknowledged in its UN submission that achieving the 2035 target "will require more stringent regulations, pricing and market policies to incentivise and enable all sectors of the economy to decarbonise".
The government is also considering new infrastructure to manage rising sea levels and more extreme weather conditions.
While Singapore is relatively safeguarded from the most severe impacts of climate change, experts predict that longer droughts, heavier rainfall and rising temperatures will become more prevalent, impacting industries and daily life.
Global leadership in climate action
Singapore's punctual submission of its 2035 NDC target by the UN deadline starkly contrasts with the global trend.
As of 11 February 2025, only 13 out of 195 countries had met the deadline, underscoring Singapore’s strong adherence to international climate agreements while major nations, including the US, retract from ambitious climate pledges.
Historically, Singapore has been cautious about setting targets without solid plans.
In 2021, many countries hastily announced net zero goals without concrete strategies.
Singapore waited until October 2022, after international frameworks for carbon credit trading were established.
The country remains uncertain about the extent to which it will utilise carbon credits — while they can aid in meeting climate goals, they are often controversial as they permit nations to claim emission reductions accomplished elsewhere instead of through direct local actions.
Nonetheless, Singapore is committed primarily to domestic emission reductions.
Grace Fu, Minister for Sustainability and the Environment, stresses the importance of collective effort.
"The government will lay the foundations for a green Singapore that is climate-friendly and climate-ready," she says.
"But we will only make headway if this is a shared vision and if we all take collective steps along this journey. I invite businesses to partner us in being catalytic agents to the transition."
Despite contributing just 0.1% to global emissions, Singapore's leadership in climate action is significant.
The 2035 target reflects both the urgency of the crisis and Singapore’s commitment to a structured, long-term approach rather than reactive policy changes.
With global climate action facing challenges, Singapore’s stance reminds us that decisive and consistent commitments are still achievable in today's complex political and economic landscape.
"I invite everyone to partner us in building a green nation, together," Grace says.
