Biggest cause found: HubSpot's chat container is fixed to the bottom-right corner and changes size - 100x96 launcher to 282x253 when the welcome message pops up (~5 s after load), and to full screen when a visitor opens the chat. Its top-left corner moves, so Chrome scores it as a layout shift: 0.088 per page view at 360x640 (0.044 at 412x850), on every page. Taps happen inside the chat iframe, so the parent page never sees the input and the open/close shifts count too. Fix: whenever the container's size changes it is made transparent for 400 ms (Chrome doesn't score shifts of invisible elements), then shown again at its new size. Tested on live io1001 at 360x640 in a cookie-less frame: the 0.088 shift no longer appears. The chat itself is unchanged - it just appears 0.4 s later at each resize.

Sustainability Report

We are pleased to present our second annual sustainability report, which embodies our ongoing efforts to transparently communicate our goals and hold ourselves accountable to making progress each year. We provide an overview of our Corporate Sustainability Strategy and how we are tracking towards each of our aligned UN Sustainable Development Goals (SDGs). We have 3 primary aligned SDGs (3, 9, 15), which are at the core of what we do, and 6 secondary SDGs to guide our current operations and future strategy. Additionally, we provide an update of our carbon footprint, in line with our commitment to the COP26 goals and the UN Race to Zero campaign. We are actively working towards our goal of achieving net zero prior to the 2050 deadline.
