Where 3.1 comes from

Derived by open-climate.ai

Σ 3.1: Syke prints the two parts separately; open-climate.ai adds them up. recycling credit stays beside it.

Reporting this kilogram under the GHG Protocol

This period

Bought as a capital good that you keep, it is Scope 3, category 2, counted in the year you buy it.

When the building you own is taken down, its waste is category 5, waste generated in operations, in the year of demolition.

Syke does not count any of this in the figure for one kilogram.

Gases

Syke publishes this factor as CO₂e only, with no split by gas. The CO₂e counts fossil carbon only; biogenic CO₂, biogenic methane and land-use carbon are left out.

From Syke's record to a comparable factor

Syke publishes the two parts; open-climate.ai added them up to this total. Here is each field as printed and what open-climate.ai made of it.

The total and its parts

Each part has its own page, with its own years and source record. Never add a part to the total.

About this factor

From Syke

Tuotteen suurin hiilipäästöjen lähde on sinkitty teräs, koska sen massaosuus on suuri. Vaikka alumiinin massaosuus tuotteissa on pieni, alumiini vaikuttaa merkittävästi tuotteen GWP-arvoon. Tuotteiden pääpiirteet, niiden valmistuksenaikaisiin hiilidioksidipäästöihin vaikuttavat tekijät ja nykyinen markkinatilanne on selvitetty markkinatutkimuksen, aiempien tutkimusten ja Taltekan haastattelun avulla.
