The European Union's greenhouse gas emissions increased by 1% in 2025 compared to 2024, reaching 3.34 billion tons of CO2 equivalent. While emissions have decreased by 17% since 2015, the recent rise highlights slowing progress, with calls for accelerated electrification in transport and heating sectors to reduce fossil fuel reliance.

Greenhouse gas emissions reached an all-time high of 56.8 billion tonnes of CO2 in 2024, according to a study. Climate scientists have called for urgent action to address the rising emissions.

The 2025 IGCC report reveals a record-high 10-year average of Earth's energy imbalance, driven by rising greenhouse gas emissions. Atmospheric concentrations of CO2, methane, and nitrous oxide reached new highs in 2025, with emissions reaching 56.8GtCO2e in 2024. The report highlights the accelerating pace of global warming due to human activities like fossil fuel use and deforestation.

Two new studies find that China's Belt and Road Initiative has a significant climate impact, with over half of its emissions coming from steel production, primarily in China. The studies emphasize the need for strong regulations and incentives to reduce greenhouse gas emissions from Chinese manufacturing.

Scotland's greenhouse gas emissions decreased by 1% in 2024 compared to the previous year. However, the pace of progress in reducing emissions has slowed.

Rwanda has reduced 1.5 million tonnes of greenhouse gas emissions, achieving 36% of its 4.4 million-tonne reduction target set for 2030 under the national climate action plan, according to the Rwanda Environment Management Authority (REMA).

President Donald Trump announced efforts to revive the US coal industry, claiming coal would reduce energy costs despite evidence that it is one of the most expensive electricity sources in the US. The article highlights coal's decline, noting it now produces 15% of the nation's electricity, with renewables like wind and solar becoming cheaper alternatives. Coal also faces criticism for high greenhouse gas emissions, toxic pollutants, and hazardous byproducts.

Ed Miliband proposes a legally binding target to cut UK greenhouse gas emissions by 87% by 2040. The proposal is expected to spark political conflict with opposition parties over net zero policies.

California has updated its cap-and-invest climate program, which will influence the state's approach to reducing greenhouse gas emissions and the allocation of billions in revenue. Critics argue the changes represent a retreat from previous climate goals.

California has updated its cap-and-invest program, which governs greenhouse gas emission reductions and the allocation of billions in revenue. Critics argue the update represents a retreat from aggressive climate action.

California updated its cap-and-invest program to determine the pace of greenhouse gas emissions reductions and revenue distribution. Critics argue the change represents a retreat from prior climate goals.

The SEC is proposing to repeal a 2024 rule requiring public companies to report greenhouse gas emissions and climate risks, claiming it exceeds the agency's authority and imposes unjustified costs. Environmental groups argue the move deprives investors of critical climate risk data, while the repeal aligns with broader environmental rollbacks under President Donald Trump's administration. The rule was initially approved on a party-line vote with three Democratic commissioners supporting it and two Republicans opposing.

The Securities and Exchange Commission proposed repealing a rule requiring public companies to report greenhouse gas emissions and climate risk, part of efforts to undo Biden-era climate regulations.

Paul Atkins, the chairman of the Securities and Exchange Commission, moved to eliminate a Biden-era climate rule requiring US firms to report on global warming risks and greenhouse gas emissions. The rule was criticized as growth-strangling red tape.

The repeal of the EPA’s endangerment finding is unlikely to mitigate the rise in chronic disease rates, which are expected to worsen as greenhouse gas emissions increase. This trend will exacerbate climate impacts like extreme heat and wildfires, further harming public health.

Hong Kong’s first astronaut will use a locally developed observatory on the Tiangong space station to monitor greenhouse gas emissions. The imaging equipment will help identify emission sources and intensities, aiding carbon reduction efforts in the Greater Bay Area and mainland China.

President Trump signed an executive order on Thursday that loosens federal environmental regulations requiring grocery stores and air conditioning companies to reduce greenhouse gas emissions from cooling equipment. This action reverses a Biden-era environmental rule aimed at curbing emissions from the cooling sector.

Denver is trying to reduce greenhouse gas emissions from its buildings by using a new solution that involves sewage. The city's largest source of emissions is its buildings, which require a lot of fossil fuels for heating and cooling. Denver's plan aims to heat and cool buildings without fossil fuels.

A new study finds that adopting a vegan diet can reduce greenhouse gas emissions by 55%. This significant reduction highlights the potential impact of dietary choices on environmental sustainability. The research suggests a substantial decrease in emissions from food production and consumption.

A study found that adopting a vegan diet can reduce greenhouse gas emissions by 55%. This significant reduction highlights the potential environmental benefits of choosing plant-based food options. The research suggests that individuals can make a substantial impact on the environment through their dietary choices.

A WIRED analysis reveals that gas-powered data center projects linked to OpenAI, Meta, Microsoft, and xAI could emit over 129 million tons of greenhouse gases annually, surpassing emissions from entire nations.
