What has got us talking this week?

Transition Plan Taskforce Seminar

Where: Online, for LSA Members only

When: 1st February, 12-1pm

Net zero and transition plans have become new norms in private sector ambition. An increasing number of organisations are making public commitments to reach net zero. Yet existing transition plans vary in detail and quality, limiting the ability of stakeholders to assess their credibility.

There is significant demand from the private sector for standardised, high quality plans to make better-informed decisions about how to allocate capital. This will support the UK’s transition to net zero.

Find out more about the Transition Plan in this LSA/TPT seminar, featuring Jacques Morris – Secretariat Team Leader and Policy Lead and Ira Poensgen, Secretariat Research Assistant.

    Simply collect your emissions data for energy, water, waste, travel, procurement and scope 3 supply chain – and the tool does the rest. Using the latest DEFRA emissions factors the Carbon Calculator gives you an accurate picture of your annual CO2e emissions.
