To support the Paris process at #COP30, a report by @CtrGlobSust, @WWF_Mexico & Tempus Analitica presents plausible, high-ambition pathways for Mexico to reduce emissions by 47%-51% by 2035 and achieve net-zero emissions by 2050: go.umd.edu/Mexico2035Ambition
An infographic titled, "To Deliver Significant Emissions Reductions by 2035, Key Policy Actions for Mexico Include:" with an icon of a sun, plant, recycling, and electric vehicles with the text, "Accelerating solar and wind buildout; Adopting sustainable agricultural practices; Advancing solid waste management; and Incentivizing EV adoption through vehicle subsidies".

As the world gathers in Brazil at #COP30 to discuss ramping up climate action, a new @americaisallin.com report led by @ctrglobsust.bsky.social finds that with enhanced subnational action and a reengaged federal government, the US can cut emissions by 56% by 2035: go.umd.edu/USPathway...
A field of solar panels on green grass with the text, "All In's New Report Demonstrates that Significant U.S. GHG Emissions Reductions Are Still Achievable by 2035." Additional text below reads, Despite uncertainty around recent policy changes and economic dynamics, opportunities still exist to make progress and ramp up climate ambition to meet national and international climate goals. GHG emissions reductions possible by 2035 through enhanced high-ambition climate action from cities, states, communities, and businesses, combined with renewed federal engagement.
